WINDOW CONSTRUCTION.

Specification of Letters Patent.

To all whom t may concern Be it known that l, CHARLES SINGER, a citizenof the United States, residing at Winfred, in the county of Lake andState of South Dakota, have invented certain new and useful Improvementsin Window Constructions, of which .the following is a specification.

My present invention relates to improvements in window constructions andin particular to the type involving storm sashes.

My main object is to provide .a storm window which consists ofcooperating sections or double sashes designed especially with a view tofacilitating the handling of the window in removing the same oroperating itsmembers when in use to either close or open them forVentilating purposes. words, the storm window members of my device areslidable relative to each other in a similar manner to the ordinarywindow sashes but are so arranged that they may be disconnected 'fromthe window frame quickly and from either theinterior or eX- terior ofthe window frame.

The above and other objects as may hereinafter' appear are attained bythe novel construction, combination, .and arrangement of parts to behereinafter specifically described and claimed. i

Reference'will now be had to the accompanying drawings forming a part ofthis specification, wherein: l'

Figure 1 is an elevation of a window construction forming the embodimentof my invention. Fig. 2 is a vertical sectional View on the line 2-2 ofFig. l and showing more clearly the action of the swinging frame for aninterior window sash of this device. Fig. 8 is a front elevation of thewindow construction with the upper storm window section removed and thelower cooperating section in elevated position, parts being broken awayto show the interlocking guide projections for the last-mentioned sash.Fig. 4. is a vertical sectional view taken on the plane indicated by theline 4 4 of Fig. 3, but showing the lower storm window sash lowered andthe upper storm window sash replaced Fig. 5 is a horizontal sectional Inother 4 view on the line 5 5 of Fig. `1; and Figs.

6 and 7 are perspective views of the slidable catches or buttonsemployed in this device.

rlll`hr oughout the following detailed descrlptlon, and on the severalfigures of the drawings, .slmilar parts are referred to by likereference characters.

Referring to the drawings and specifically describing the embodiment ofmy invention, A denotes the main body of a window frame which may be ofthe usual type and form, but which preferably consists of a dow sash F'which have at their meeting` en ds interlocking metal strips Gr, Gconstituting weather strips of a known type. It will be observed thatthe interior window sashes E and F may be easily removed from theirsliding positions as most clearly lshown in Fig. 2 wherein the lowersash is raised above its lowered position until it is disposed in theswinging frame B which may then be swung outwardly to enable theextraction of this lower sash therefrom. Zlhe upper sash E may then bedisplaced 1n an obvious manner by lowering the same to a point where itmay be withdrawn, the parting strip for guiding the sashes being carriedby the swinging frame B for this purpose. These sashes E and F are heldat adjusted positions by means of spring plungers H.

The storm window elements of my window construction comprise the lowersash member l and the upper sash or section 2, the latter being disposedbetween the guide strips 3 attached to the exterior surface of the frameat. its upper portion. It will be Patented tray es, raie. l

Btl

observed particularly by reference to Fig. 1` that these guide stripsconverge toward the upper portion of the frame and the upper sash 2 islikewise of converging form on its side edges soas to seat easily inplace between said guide strips 3. This is a special feature of myconstruction since it eliminates any likelihood of binding of the upperstorm window sash and facilitates the removal of this sash as will-hereinafter more fully appear. The upper storm window sash 2 is held inelevated position normally by means of sliding catches 4 which areslotted and attached to the main frame A by screws 5 or similarfastening 'members. These sliding catches are best shown in Figs. 6 and7 and comprise metal strips bent to form supporting flanges and finger Ipieces for manipulating the same and other similar sliding buttons 5 areattached to the frame A at intervals adjacent to the edge of the lowerstorm window sash l and these catches 4 and 5 guide the lower sash inits sliding action with respect to the upper sash 2 as well as supportthe latter in its elevated position, hereinbefore mentioned. The meetingends of the storm window sashes 1 and 2 are also provided withinterlocking metal strips 7 to perform the usual weather strip functionand it will be obvious from this description that a very adequate stormprotection is afforded by the arrangement. The lower sash 1 ashereinbefore premised, may be raised and locked at adjusted positions4by means of a pivoted latch 8 which engages with a serrated strip 9secured to the side of the frame A, and the frame is provided at eachside and adjacent to its upper portion with projections 10 which operatein grooves 11 formed in the lower sash 1 when said sash .is raised. Thisinterlocking action prevents the lower sash from accidentaldisplace-ment when being raised and particularly when the upper sash 2is removed.

One of the essential characteristicsof this construction is the'utilization of sectional storm window members that enables an operatorto remove them from the interior of they house to which they may bea'ttached. This is accomplished by raising the lower storm window sashafter opening the interior window sashes and holding it at its extremeupper position by engaging the pivoted button member 11 beneath itsedge. The sliding members 4 are then moved outwardly from beneath thelower edge of the upper sash 2 which will then drop down-V wardly andwhen the upper portion reaches a point intermediate the length of theguide strips 3 where the distance between said strips is equal to theupper edge of the sash i 2 it will be possible to entirely remove saidsash from its guide members, and carry said sash through the windowframe. By moving the sliding members 5 outwardly and disengaging thelocking member 11 from the lower sash 1, this member may be lowereduntil the projections 10 are disengaged from the slots 11 whereupon saidsash may be carried through the window frame.

The window construction of this invention is of a very simple characterand may be cheaply manufactured because it vdocs not radically departfrom an ordinary window construction in its essential characteristics,and the facility with which its elements may be manipulated enhances itscommercial value. It is particularly pointed out that instead of a stormwindow the sashes 1 and 2, which 4have been described, might equally aswell constitute screens so that the construction may be consideredeither a storm window construction or a sectional screen constructiondepending upon what the sashes are provided with, that is whether glassor screening.

Having thus described my invention, what I claim as new is:

1. In combination, a. window frame, a

'storm window therefor comprising a relatively stationary section and amovable section, exterior guide strips connected to the frame forcoperation with the stationary section normally preventing outwarddisplacement thereof, and a plurality of catch members connected atintervals to the face of the frame adjacent to the movable section forguiding normal movement of the last mentioned section and preventingoutward displacement thereof when the stationary section is displaced,certain of said catch members being arranged to engage and hold thestationary section in its normal 'position aforesaid.

2. In combination, a window frame, a storm window therefor comprising arelatively stationary section and a movable section, exterior guidestrips connected to the frame for coperation with the stationary sectionnormally preventing outward displacement thereof, a plurality of catchmembers connected to the frame adjacent to the movable section forguiding normal movement of the last mentioned section and slidablelaterally for disengagement from the movable section to permit ofoutward' displacement of the last mentioned section, certain of saidcatchI members being disposed adjacent the lower edge of the stationarysection for engaging the latter to'hold the same in its normal positioncoperative with the guide strips aforesaid, interlocking connectionsatthe meeting edges of the stationary and movable sections preventingaccidental displacement of said movable section when the slidablecatches are disengaged therefrom,l and projections on the frame adaptedto interlock with the edges of the movable section when the latter is inraised position Jfor displacing the stationary 'sec/ tion whereby tocoact with certain of the slidable catches to hold the movable sectionW.
